In Seattleland, you might try investigating what you can leech from the University of Washington, officially or surreptitiously -- they've got a really good CS program. If nothing else, there's the twice weekly speaker seminar which is pretty well open to the public... though that won't teach you basic theory. (There's also a good professional master's program, though that wouldn't do you any good until you have a job with tuition reimbursement.)

You could also start a company. :P
